Cross-posting to r-help is not appropriate. (This is especially important when the answer was to be found in the R-FAQ.)  Please wait for an answer on SO if you choose to post there first. (Or if you have chosen to ignore this request, then at least have the courtesy to post a SOLVED notice here so people know that it has already been answered there.)
